I bought this for a smaller heli that I wanted to use the miliamp sensor on but didn't need the bigger wires that come on the miliamp sensor. It was very easy to solder on the smaller wires and cover it back up with this kit. It was so easy, in fact, and looks so tidy that I will now do the rest of my helis. This kit comes with enough material to do three sensors so I'll be set for a while.
